Well then, it's time for you to go wireless. There are several options out there for Arduino wireless connectivity, but the easiest and most elegant is definitely the XBee RF module.

The Blues Wireless for Arduino Opta module represents a significant step forward in this evolution, providing a powerful and accessible solution for a wide range of industrial applications.

Offering a cost-effective Arduino compatible board with the W600 WiFi module. – Arduino Zero Compatible/ Adafruit Feather Compatible – 2.4GHz onboard WiFi module supports 802.11 b/g/n ...

For the last few years, a new low-power wireless communication standard has been coming on the scene, and now this protocol — LoRa — will soon be available in an Arduino form factor.

It has a similar form factor (67 x 25mm) and a Microchip SAM D21 32-bit Cortex-M0+ microcontroller as the previous MKR1000 and MKRZero boards. But this board has been designed for low power IoT ...

A Swedish software engineer — Johan Kanflo — has made a wireless Arduino clone called AADuino, which is the size of an AA battery. Kanflo explains that the AADuino has an onboard RF module ...

The brains of the machine is an Arduino Deumillanove and an XBee module. The unit can be controlled by a web interface or it can run completely standalone.

And, there are cheap wireless modules that attach over serial and use the AT command series to connect and transfer data. I'd probably use one module to run 5 or 6 sensors, conformal coated and ...
